SunGuard 4 From Hotwire Enterprises

When it comes to "bang for the buck", this little controller is a nuclear bomb. The Morningstar SunGuard 4 (SG-4) is the perfect small job controller, and here's why:

• First of all, the SG-4 has no settings (it comes preset for sealed batteries) so there is nothing to fiddle with and potentially cook or undercharge your batteries!
• Second, it is extremely rugged. Potted in epoxy and supplied with outdoor rated wire, this baby can take on Typhoon Mary.
• Third, it uses the same Pulse Width Modulation circuitry as its bigger cousins, the SunSavers. You will always get the most from your solar panel.
• Fourth, it is manufactured to ISO 9002 quality programs for a long and productive life.
• And last, but not least, is the price. This puppy is a major bargain. At only $29.95, this unit pays for itself in a hurry.

Hearty thanks to Larry Cooper, editor of The Kyocera Sun and author of this enthusiastic gem!
